ifomey Patented Nov. 1, 1932 PATENT OFFICE ADOLF H. SAAB, JR., F OMAHA,NEBRASKA TIME CONTROLLED SWITCH Application filed May 15, 1931.

This invention relates to new and useful improvements in switches, andmore particularly to a switch for controlling radios, lighting circuits,and various other electrical systems, and devices.

The principal object of this invention is to provide a time-controlledswitch employing a multiplicity of connectors which can be readilymanipulated to complete the timing section, so that an electrical systemor device can be operated over a predetermined period of time.

During the course of the following specification and claim, otherimportant objects and advantages of the invention will become apparentto the reader.

In the drawing Figure 1 represents a front elevational view of the clockand switch mechanism.

Fig. 2 represents a fragmentary front elevational view of the clock andswitch mechanism.

Fig. 3 represents a perspective view of one of the conductor segments.

Fig. 1 represents a fragmentary detailed sectional view takensubstantially on the line 55 of Fig. 1.

Referring to the drawing wherein like numerals designate like parts, itcan be seen that the invention involves a clock which includes a casino;5 in which the usual clock mechanism is housed. Numeral 7 represents theusual hand setting key.

The casing 5 has a flange 10 at the front side of the block and thisflange is provided with an annulus 11 having an outwardly projectingcircumferentially extending flange 12. The flanges 10 and 12 as well asthe annulus 11 serve to provide a guide plate for the reception of thecurrent conductive segmental blocks 13, each of which is provided with afinger engageable lug 14 at its outer end.

Referring to Fig. 1, it will be found that the hour hand 15 does notengage the block 13, but that the minute hand 16 is provided with asmall contact head 17 at its outer end, offset for wiping engagementwith the blocks 13, when the blocks are properly braced in between theflanges 10 and 12.

Serial No. 537,703.

Obviously, the blocks 13 can be assembled as in the manner shown in Fig.1, for the continuous reception of a program in the event the switch ishooked up to a radio receiver. Should it be desired to cut out a certainprogram over a period of fifteen minutes, the blocks opposite the timeperiod during which the particular undesired program is to bebroadcasted, are removed, so that when the hour hand arrives at thispoint, the circuit will open and the hour hand will con tinue until itreaches the nextblock, over this space from which the blocks have beenremoved.

While the foregoing specification sets 5 forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having thus described my invention, What I claim as new is In a clockswitch, a clock casing provided with a dial opening, the edge portion ofthe casing at the opening being provided with an inwardly disposedcircumferentially extending flange, an annular wall extending outwardlyfrom the flange and provided with a backwardly disposedcircumferentially extending flange defining a trough, and removablydisposed conductor blocks in the trough for engagement by one hand ofthe clock.

In testimony whereof I aflix my signature.
